Kristen Stewart shows off a little leg as she sits in on a Q&A session before the premiere of Welcome To The Rileys premiere during the 2010 Los Angeles Film Festival at Regal Cinemas in Los Angeles on Friday night (June 25).

The 20-year-old actress traded in her heels for comfortable chucks during the session. Smart girl!

Kristen has been at a premiere almost every night this week! On Wednesday, she hit up Love Ranch and on Thursday, she premiered Eclipse with the rest of her Twilight cast.
